Frequently Asked Questions - Atmo K-34454 KOHLER

How to install the Atmo K-34454 fan?

Follow the steps in the manual: prepare the hole aligned with a joist, install the duct connector, connect the electrical wires according to the diagram (fan only or with lighting), attach the junction panel and fan housing, then install the cover. Make sure to cut off power before any intervention.

What type of duct to use for this fan?

It is recommended to use a 6-inch (152 mm) rigid metal duct for optimal airflow. Avoid smaller ducts and prefer the shortest and straightest path possible.

My fan is not working, what should I do?

First check the circuit breaker and electrical connections in the junction box. If everything seems correct, the motor may be defective and the fan needs to be replaced.

The fan noise has increased, how to fix it?

Increased noise may come from a loose nut (tighten with a wrench), dust buildup (clean the blower), or a blocked vent (clean the vent).

The fan light does not turn on (model with lighting)?

Check that the fan is powered and that the lamp cover wire is properly connected to the housing. If the LED panel is damaged, it needs to be replaced. In case of flickering, the dimmer used may not be compatible with LEDs; use a suitable TRIAC dimmer.

Can I use a dimmer with this fan?

Caution: This fan must not be used with a solid-state speed control (standard dimmer). For models with lighting, use a TRIAC dimmer recommended for LEDs if needed.

What is the warranty for the Kohler Atmo K-34454 fan?

This product has a three-year limited warranty. For details and conditions, visit kohler.com/warranty or contact customer service.

How to clean the fan?

Disconnect power. Clean the blower and vent to remove dust. Use a soft cloth and avoid abrasive products. Tighten the fan nut if necessary.

Can I install this fan above a bathtub?

Yes, provided it is marked as suitable and connected to a circuit protected by a ground fault circuit interrupter (GFCI). Follow local codes.

READ AND FOLLOW ALL INSTRUCTIONS

WARNING: When using electrical products, basic precautions should always be followed, including the following:

DANGER: Risk of electric shock. Disconnect the electricity to the working area at the main breaker panel before performing installation steps for hardwiring.

WARNING: Risk of electric shock. Disconnect the power before servicing.

WARNING: Risk of injury or property damage. To reduce the risk of fire or electric shock, do not use this fan with any solid-state speed control device.

CAUTION: Risk of personal injury. For general ventilating use only. Do not use to exhaust hazardous or explosive materials and vapors.

IMPORTANT! The R value of the ceiling thermal insulation used must not exceed R60.

WARNING: To reduce the risk of fire, electric shock, or injury to persons, observe the following:

Use this unit only in the manner intended by the manufacturer. If you have questions, contact the manufacturer.

Before servicing or cleaning unit, switch power off at service panel and lock the service disconnecting means to prevent power from being switched on accidentally. When the service disconnecting means cannot be locked, securely fasten a prominent warning device, such as a tag, to service the panel.

Installation work and electrical wiring must be done by qualified person(s) in accordance with all applicable codes and standards, including fire-rated construction.

Sufficient air is needed for proper combustion and exhausting of gases through the flue (chimney) of fuel burning equipment to prevent back drafting. Follow the heating equipment manufacturer's guideline and safety standards such as those published by the National Fire Protection Association (NFPA), and the American Society for Heating, Refrigeration and Air Conditioning Engineers (ASHRAE), and the local code authorities.

When cutting or drilling into a wall or ceiling, do not damage the electrical wiring and other hidden utilities.

Ducted fans must always be vented to the outdoors.

If this unit is to be installed over a bath or shower, the unit must be marked as appropriate for the application and be connected to a GFCI (Ground Fault Circuit Interrupter) - protected branch circuit.

Follow all local plumbing, building, and electrical codes.

SAVE THESE INSTRUCTIONS

The ducting has a strong effect on the air flow, noise, and energy use of the fan. Use the shortest, straightest duct routing possible for best performance, and avoid installing the fan with smaller ducts than recommended. Insulation around the ducts can reduce energy loss and inhibit mold growth. Fans installed with existing ducts may not achieve their rated air flow.

6^ (152 mm) round rigid metal duct is recommended for best performance.

Verify that the duct joints and exterior penetrations are sealed with caulk or other similar material to create an air-tight path, minimize building heat loss/gain, and to reduce the potential for condensation.

Place or wrap insulation around the duct and/or fan to minimize possible condensation buildup within the duct, as well as minimize building heat loss/gain.

1. Prepare the Site

IMPORTANT! One side of the hole must align with a joist.

NOTE: It is recommended that an additional 2x6 vertical support block is constructed on the side of the hole opposite the joist. Use the provided support block if an additional 2x6 vertical support cannot be constructed.

Remove the old fan if installing in an existing fan location.
Patch or enlarge the ceiling hole using the provided template taking care to align one edge of the hole with a joist.
Install a 2x6 vertical support block on the edge of the hole opposite the joist. If this is not possible, install the provided support block using the following steps.

Support Block Installation

NOTE: The screws used to attach the support block to the finished ceiling must be located 1/2'' (13 mm) or closer to the edge of the hole to allow the fan box flange to cover the screws.

Align the support block with the edge of the ceiling hole inside the finished ceiling.
- Secure the provided support block behind the ceiling drywall using screws (not provided).

2. Install the Duct Connector
